How to compare and update libraries in local Maven repository

I'm looking for a way to compare then possibly update (i.e. get newer versions of) the libraries/plugins that are (a) used by a given business project of mine or (b) stored in my local repository, against a remote repository.

For example to illustrat开发者_高级运维e use case "(b)", my application has been using some-lib-1.1 for some time. One day some-lib-1.2 gets available. Since my application can use many libraries, I'd like an automated tool that compares the versions of the libraries used by a given project against the ones available in the configured remote repositories. The tool could generate a report such as : "For library 'some-lib', you use version '1.1', newer available versions are: '1.1.1', 1.2'"

Does Maven support this? How can I achieve this?

Thank you for your time.

You should take a look at the Maven Versions Plugin. You can create reports with it. Take a look here.
